CORN-PLANTER.

SPECIFICATION forming part of Letters Patent N 0. 405,498, dated June18, 1889.

Application filed February 19, 1889. Serial No. 300,425- (No model.)

T to whom, it may concern.-

Be it known that we, J AMES R. PATTERSON and lVIARSHAL T. FOSTER, bothof Madison,

in the county of Greenwood and State of Kansas, have invented a new anduseful Improvement in Corn-Planters, of which the following is a full,clear, and exact description.

Our invention relates to an improvement in corn-planters, and has forits object to provide a simple and effective check-row attachment forcorn-planters, an improved device for reciprocating the seed drop-bar,and means for throwing the marker out of engagement with the ground whendesired.

The invention consists in the novel construction and combination of theseveral parts, as Will be hereinafter more fully set forth, and pointedout in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters and figures of referenceindicate corresponding parts in all the views.

Figure l,is a plan view of the corn-planter. Fig. 2 is a centralvertical section. Fig. 3 is a transverse section through the axle nearone of the wheels, illustrating the said wheel in position to revolvefreely upon the axle; and Fig. 4. is a similar View, in which the wheelis shown as geared to the axle.

In carrying out the invention the seedboxes 10, which may be of anyapproved construction, are located upon the frame 11, Which seed-boxesare provided with the usual form of reciprocating drop-bar 13. The frame11 is supported upon runners 14, and to the rear of said frame a secondframe 15 is hinged, the front cross-bar 16 of said rear frame beingprovidedwith a vertical yoke 17.

In the rear frame 15 an axle 18 is journaled, having a crank-arm 19,formed therein opposite the frame-yoke 17, as best shown in Fig. 1, andat one end of the crank-arm a ratchet-wheel 20 is secured to the saidaxle. A lever 21 is loosely mounted upon the axle .provided with a dog22, capable of engagement with the ratchet-wheel, which lever 21extends, preferably, beyond the rear frame, and by elevating the leverthe axle may be readily rotated.

Near each end of the axle 18, outside of of each drive-wheel, atoppositesides of the hub, a pawl 25 and 26 is respectively pivoted, which pawlsare normally held in engagem cut with the ratchet-wheels 24 by means ofsprings 27 or equivalent devices, as best illustrated in Figs. 3 and 4.

Between each ratchet-wheel 24 and the opposed faces of the drive-wheels23 a shiftingarm 28 is pivoted upon the axle, the ends of which arm arebent inward, as bestillustrated at a in Fig. 1.

\Vhenit is desired to permit the drivewheels to turn loosely upon theaxle 18-as, for instance, in going to and from a field-the shifting-arm28 is so turned that the ends (1,.

will be brought in contact with the pawls 25 and 26, disengaging themfrom the ratchetwheels 24, as illustrated in Fig. 3. This is ordinarilyaccomplished when the shifting-arm is located diagonally of the frame,and when the said arm is carried parallel with the frame,

as shown in Fig. 4, the pawls 25 and 26 are free to act. I

At the rear of the forward frame 11 a vertical shaft 30 is journaled insuitable bear ings 31, from the upper end of which shaft an arm 29extends forward and is pivotally secured to the center of the drop-bar13, as best shown in Figs. 1 and 2. To the lower end of the shaft 30 anarm 32 is secured, said arm being adapted to project at a right angle tothe arm 29. To the outer end of the arm 32 is pivotally attached apitman 33, which pitman is pivotally secured to the crank-arm 19 of theaxle 18. The extremities of the axle 18 project outward beyond the hubsof the drive-wheels, and upon each extremity of the axle a marker 34 isrigidly secured, consisting of a bar equivalent in length to thediameter of the drive-wheel, and provided at each end with anoutwardly-extending shoe 35, as best shown in Fig. l. The markers 34being adapted to make an impression in the soil at each half-revolutionof the wheel, the dropping-chute of the feed-box is preferably locatedat such a distance in advance of the The markers 34 are so attached tothe axle.

that when the seed-aperture of the drop-bar registers with the similaraperture of the seedbox one shoe 35 will be in position to strike theground. The lever 21 is used for dropping the first hill and-foradjusting the markers after turning, as it is evident, by themanipulation of the leyer 21, for instance, carryin g the same towardthe front of the machine, the axle 18 may be revolved without turningthe drive-wheels, whereby the seed drop-bar may be reciprocated whilethe machine is stationary. The lever 21 is adapted to be locatedadjacent to the drivers seat.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent 1. In a corn-planter, the combination, with anaxle provided with a crank-arm, a seed drop-bar, a vertical shaftjournaled to the rear of the drop-bar, and connection betweenthe upperend of the said shaft and the drop-bar and the lower end of the shaftand the crankarm of the axle, of drive wheels loosely mounted upon theaxle, a marker rigidly secured to the ends of the axle outside of thedrive-wheels, a ratchet-wheel rigidly secured to the axle near the innerface of each drivewheel, and spring-actuated pawls pivoted to thedrive-wheels and capable of engagement with the said ratchet-wheels allcombined for operation substantially as shown and described.

2. In a corn-planter, the combinatiomwith an axle provided with acrank-arm,-a seed drop-bar, a vertical shaft j ournaled to the'rear ofthe drop-bar, and connection between the upper end of the said shaft andthe drop-bar and the lower end of the shaft and the crankarm of theaxle, of drive wheel's loosely mounted upon the axle, a marker rigidlysecured to the ends of the axle outside of the drive-wheels, aratchet-wheel rigidly secured to the axle near the inner face of eachdrivewheel, spring-actuated pawls pivoted to the drive-wheels andcapable of engagement with the said ratchet-wheels, and a shifting-armpivoted upon the axle between the ratchetwheels and the drive -wheelsand having curved ends, substantially as shown and described.

3. In a corn-planter, the combination, with a seed drop-bar, an axleprovided with a crank-arm, and a connection, substantially as shown anddescribed, between the crank-arm of the axle and the drop-bar, ofdrive-wheels loosely mounted upon the axle, a ratchetwheel rigidlysecured to the said axle near the inner face of each drive-wheel, and anintermediate ratchet- Wheel also secured 'to the axle, a marker securedto each extremity of the axle outside of the drive-wheels, pawls pivotedto the drive-wheelscapable of engagement with the outer ratchet-wheelsof the axle, shifting-arms loosely mounted upon the axle and havingcurved ends, and alever held to revolve upon the axle adjacent to theintermediate ratchet wheel and provided with a dog adapted to engagewith the said wheel, substantially as and for the purpose Specified.
